[Non-invasive derivation of potential of the bundle of His from the body surface (author's transl)].
In 17 of the 28 patients a surface potential of the bundle of His could be differentiated. Pharmacological tests with verapamil and ajmaline raised the number of positive body surface recordings of the bundle of His to 22 out of 30 (=73%). In 11 of the 30 subjects (=37%) depolarizations of the Tawara bundle branches were recorded in addition. Two possible applications of this method are discussed: follow-up of patients with AV-block and supervision of negative dromotropic cardiac medication.
